More on the Longevity Project

Cheerful children, alas, turned out to be shorter-lived than their more sober classmates. The early death of a parent had no measurable effect on children’s life spans or mortality risk, but the long-term health effects of broken families were often devastating. Parental divorce during childhood emerged as the single strongest predictor of early death in adulthood. The grown children of divorced parents died almost five years earlier, on average, than children from intact families.
